Researchers in the Sheffield Centre for Robotics, jointly established by the University of Sheffield and Sheffield Hallam University, have been working to program a group of 40 robots, and say the ability to control robot swarms could prove hugely beneficial in a range of contexts, from military to medical.
Swarms of robots acting together to carry out jobs could provide new opportunities for humans to harness the power of machines, explain the researchers.
The researchers have demonstrated that the swarm can carry out simple fetching and carrying tasks, by grouping around an object and working together to push it across a surface. The robots can also group themselves together into a single cluster after being scattered across a room, and organize themselves by order of priority.
Dr Roderich Gross, head of the Natural Robotics Lab, in the Department of Automatic Control and Systems Engineering at the University of Sheffield, says swarming robots could have important roles to play in the future of micromedicine, as ‘nanobots’ are developed for non-invasive treatment of humans. On a larger scale, they could play a part in military, or search and rescue operations, acting together in areas where it would be too dangerous or impractical for humans to go. In industry, robot swarms could be put to use, improving manufacturing processes and workplace safety.
The programming that the University of Sheffield team has developed to control the robots is simple. For example, if the robots are being asked to group together, each robot only needs to be able to work out if there is another robot in front of it. If there is, it turns on the spot; if there isn’t, it moves in a wider circle until it finds one.
